Summary

DescriptionTrinity Test - 100 Ton Test - High Explosive Stack 002.jpg

English: Trinity Test. Explosive stack of the 100 Ton Test. To help in preparing the instrumentation for the Trinity shot the 100 Ton Test was fired on 7 May 1945. This test detonated 108 tons of TNT stacked on a wooden platform 800 yards from Trinity ground zero. The pile of high explosive was threaded with tubes containing 1000 curies of reactor fission products. This is the largest instrumented explosion conducted up to this date. The test allowed the calibration of instruments to measure the blast wave, and gave some indication of how fission products might be distributed by the explosion.
